28. Hirundo horreorum (Barton). Barn Swallow. 

 Rather rare, a few pairs breed about the buildings of the post. 



They arrive about the same time, but remain longer than the former. 



29. Hirundo thalassina (Swains.). Violet-green Swallow. 

 Noticed on Bear Creek, near the summit of the Blue Mountains, in 



the summer of 1876. 



30. Cotyle riparia (Boie). Bank Swallow. 



Breeds in large numbers on one of the islands in Malheur Lake, in 

 the side of a perpendicular ridge from four to six feet high. The soil 

 is sandy, and the burrows extend in from two to five feet. Some of 

 the eggs had been set on for a week when taken on May 27, 1875, 

 and one of the nests contained seven eggs, the majority five or less. 



31. Vireosylvia swainsoni Baird. Western Warbling 

 Greenlet. 



Specimens seen on but two occasions in June, 1876. 



32. Ampelis garrulus (Linn.). Northern Waxwing. 



A winter visitor. First noticed Nov. 23, 1875, amongst the 

 willows bordering Silvies River, Oregon. Quite a number were se- 

 cured between Nov., 1875, and March 1, 1876. During their stay 

 here they fed exclusively on the berries of the wild rose, and became 

 excessively fat. The sexes, in mature specimens, are exactly alike, 

 as far as the markings of the primaries are concerned. The white 

 in the female is carried around the terminal edge of the inner webs 

 of primaries as well as in the male. The black on the chin and 

 throat of the females is somewhat paler than in the males. See my 

 article in "Forest and Stream," Vol. vi, No. 2, Feb. 17, 1876. 



33. Myiadestes townsendi (Cab.). Townsend's Solitaire. 

 Rather common among the juniper groves during spring and fall, 



and in mild winters throughout the whole season. None remain here 

 during the breeding season. (See Proceedings of Boston Society of 

 Natural History, Vol. xvm, p. 155, Oct. 6, 1875.) 



34. Collurio borealis (Baird). Great Northern Shrike. 



A rare winter visitor. I took two specimens Jan. 5, 1876, both 

 young birds, following a number of Oregon snow birds. 



35. Collurio ludovicianus var. excubitoroides (Baird) • 

 A common summer visitor, and generally distributed. They 



arrive here about the 20th of March, and commence nesting about 

 the middle of May. May 22, 1876, I found two of their nests in ser- 

 viceberry bushes, not twenty feet from each other. The nests were 

 very deep, but the walls of the nest rather thin, well constructed,
